My DS gave himself a full mouth hickey by sucking a cup to his face, is that normal, probably not, abnormal, definitely not. He was so chuffed he was able to run around with a cup (plastic I may add) attached to his face!Â

MyÂ daughter thinks itÃ¢â‚¬â„¢s great that she has a callus from sucking her thumb. She shows it to EVERYONE, so I vote giving ones self a hickey is within the typical realm of being a four year old :)
